Sportsboat & Waterski International - 'Towing
at sea'
Take the strain out of towing. Dave Mallett explains
how to prepare for the unexpected and get a line.
If you use your boat regularly then it's a
sure bet that eventually you will be involved in a towing job of some sort or
another. If you are a careful owner, and very lucky, you will be towing another
boat out of trouble. After all, accidents always happen to somebody else don't
they!
However, to the rest of us you are
"someone else" and whichever end of the rope you are on, a little
knowledge and a bit of preparation can make the whole job less of a trauma.
Towing requires at least one rope and the
ability to tie a knot under pressure. Obvious though that is, a rope is the link
that is so often missing when a well-meaning boat owner meets a friend in need.
The answer is obvious - carry a rope that is not in a hopeless tangle, and keep
it somewhere where you can get at it - in a hurry!
But having found a rope we now need somewhere
to fix it, and sportsboats are not renowned for being over-endowed with strong
points from which to tow. Older boats in particular are prone to waving good-bye
to deck fittings, and marine ply boats with cleats fitted by woodscrews are
favourites, both for breaking down and needing a tow, and then for subsequently
having the cleat ripped out of them.
"Sportsboats are not
renowned for being over-endowed with strong points from which to tow."
The situation is getting better, and the
European Directive on Recreational Craft requires boats to have fittings strong
enough to take the strain of towing and anchoring.
In a rough sea coming alongside a casualty can
be inadvisable, and leaving the cockpit of the stricken boat to venture onto a
tiny, wet foredeck in order to tie a rope onto a cleat is definite "No!
No!"
Far better to have a rope permanently fixed
for'ard. Led back to the cockpit, it can be secured ready to use as a mooring
line, or for securing onto a tow rope or anchor warp, without the risk of
leaving the safety of the cockpit.
Snatching is the problem with towing that
destroys deck fittings. As the rope sags, and suddenly snaps tight again, deck
fittings come under a lot of strain. The handling of the boats involved is
dramatically affected and the tug often finds that it is now towing a length of
rope attached to a cleat, four screws and a selection of splinters! Using a long
rope helps. The sag caused by its weight absorbs shocks - it also helps to
prevent the towed vessel ramming the tug.
Snatching can be virtually eliminated by the
use of a "spring" or "angel"!
No - this does not need divine intervention it
is simply a weight, such as your spare anchor, hung around the middle of the
towrope. The weight produces a dip in the line and any surging or snatching on
the rope expends its energy in lifting the weight. It is quite possible to tow
sportsboats at planing speed in calm conditions and I like to attach the towrope
low down, onto the bow eye whenever possible, so that I am lifting the bow
rather than dragging it down, when I put the power on. Similarly instructing the
crew of the towed boat to move towards the stern of the casualty lifts the bow.
It is a common reaction for the crew of a casualty to come forward to watch the
rope, in the misguided belief that they are helping. If they do then the towed
boat will shear off wildly, first one way and then the other because you are
dragging deep sections first. When the bow of the towed boat is low in the water
it is akin to a weathervane that you are dragging wrong end first it will try to
swing the bow round to the back unless you have the crew move back so that the
bow lifts. Towing astern needs a towing point on the back of your boat and it is
better if you can centre the load with a bridle. You could do this by forming a
large loop in the end of the towrope by tying a bowline and then dropping this
loop over your two stern cleats.
"Towing alongside gives
greater control over a casualty but does need a good set of fenders unless you
are driving a RIB or inflatable boat."
Towing alongside gives greater control over a
casualty but does need a good set of fenders unless you are driving a RIB or
inflatable boat. It is really only suitable for calm conditions and I reserve
the technique for sheltered water and placing a boat alongside its marina berth.
The secret of total control in towing alongside is to make sure that the tug's
stern sticks out behind the casualty so that you have some leverage on the
turns. (See the diagram for the layout of the ropes). The strain is taken on the
diagonals, the short ropes are just to keep the boats together. The rope from
the bow of the tug to the stern of the casualty takes the weight, but the other
diagonal is needed if you are going to use reverse at all.
Other boats are not the only thing you may
meet in their time of need and I once had to tow a racehorse back to the beach
when it decided to do a runner from its trainer on the West Coast of Ireland,
where else could it happen?
Windsurfers are usually very competent these
days but even the best of them can have a problem. In all rescue situations the
safety of people comes first, way before any consideration of retrieving
property, so get the sailor into the boat before anything else. If you then
decide to tow the board you have a choice of methods.
There are, however, a couple of things to
remember. Firstly, modern sails are extremely high tech pieces of kit and do not
lend themselves to being de-rigged at sea. The second is that you must be wind
aware. Lift a sail with its trailing edge into the wind and it will become a
live thing with so much power that you cannot possibly control it. Manoeuvre the
board and your boat so that you are both facing into the wind and then bring the
sail across your boat with the board still in the water. If the edge of the sail
with the mast sleeved in it is not facing for'ard at this stage be careful and
let it roll over as the wind gets hold of it. Now you can tow the board
alongside at planing speed, with your windsurfer holding onto the mast and
looking after his own kit. There are legal niceties in towing and being towed
that all revolve around the laws of salvage. The advice generally given is when
in distress to offer the salvor your rope, and not accept his, as this shows
that you were still command of your vessel. And agree terms before accepting a
tow or you, or your insurance company, may find yourself with a hefty salvage
bill.
"...leaving the cockpit of the
stricken boat to venture onto a tiny wet foredeck in order to tie a rope onto a
cleat is a definite 'No! No!"
All this sounds like good advice but, in the
real and mercenary world, I wonder if the memories of what was said, and what
happened, may be a little different by the time both parties concerned have come
ashore. Particularly when there has been time to think about the outcome of an
insurance claim.
